What's a portable way of adding errors and warnings to configure.host?
It looks like it's just a regular shell script, so I'm not sure if
AC_MSG_WARN or AC_MSG_ERROR will work in there.

Short of setting emitting warnings and errors, the attached patch
silently enable --enable-newlib-global-stdio-streams
--enable-newlib-elix-level=1 for nvptx targets if the user didn't
specify anything else. If that solution is sufficient, I can regenerate
a patch with the complete nvptx port.

Thanks,
Cesar
